From long experience I havefoundanumber of deficiencies which, except in the present type of both single and doublespringj aw breaking his leg and thus escape, or which will permit of the jaws of the trap being brought against an object with such force as to open the jaws and allow theanimal to escape. SecondThe traps are not'provided with a guard and, therefore, thetraps-are not always arranged at a'proper position forthe springing of the jaws whenthepan ismoved and the pan may be swungby brush or-the like blowing thereagainst. Third-Thetrig ger for the pan is not loosely associated-with the trap, is liable to becomerusted and cannot be freely swung to engagement withthe keeper of the pan. Fourth.In double aw traps the trigger, which is swung over'one of the inner jaws to engage the keeper thereon also swing between the outer jaws, thus rendering this type of traps'extremely'diflicult to set and, F ifthThe spring for theinner jaws of a double trap has on its upper-arIn-a pivoted buttonthat is swingable over oneof the outer jaws when the trap is set. The button soon becomes rusted sothatthe' same cannot be freely turned and this alsocom- It is, therefore, my objectto present a trap construction which will successfully over- It is also my object to :provide means for overcoming the above mentioned deficiencies in ordinary spring jaw traps which maybe readily attached toand form part of such traps.

an upstanding ear 14 formed centrally on the depressed upper edge of one of the side members of the substantially elliptical guard 15. The guard 15 is arranged around the base and is riveted or otherwise secured to the outer faces of the upstanding ends 2 and 3 of the base. The ear 1 1. and the portion of the guard diametrically opposite said ear have spaced round openings therethrough for the ofiset ends of trunnions 16 of the arched jaws 17, respectively. One of'the jaws is designed to have swung thereover the trigger 6 which engages with the keeper 10 when the trap is set, this being, of course, ordinary to such The guard 15, below the ear 14: and at the side thereof diametrically 0pas disclosed by the drawings that is,

posite the ear is formed with depending portions 18, respectively whichare in the nature of what may be termed shoes and which rest on the ground surface and, if desired, hold the trap at an angle or permit of' the pan being arranged at a horizontal position when the trap is set. Swivelly connected to the base 1 and to the lower arm 11 of the spring there is an eye member 19 to which is connected the usual eye endgof a'rod 20. The outer end of the rod has swivelly connected thereto an eye or bail 21 to which is attached one of the end links of a chain 22, the second end link of the chain being provided with the usual ring 23 through which the holding stake is passed.

The swivel connection between the trap and the chain, as well as the guard for the chain are important features of the construction described. An animal caught in the trap will, in his movement, simply turn the trap on the eye or swivel 19 should the shoes 18, which bite into the ground surface permit such movement of the trap; The shoes serve as obstructing elements for preventing the animal moving the trap to wind the chain around the stake, but even should this be successful the trap is not retained in a rigid condition but will swing on the swivel 19, so that the animal can obtain no firm purchase which would otherwise permit him to break his leg and thus escape from the trap were the trap held from free turning movement. Another very important feature of the trap construction resides in the rounding of the confronting or biting edges of the jaws 17, and indicated by the numeral 24: thereon. The confronting edges of the ordinary trap jaws are straight, the corners thereof are not round. These sharpened corners have a biting effect upon the leg of the trapped animal during his movement of his said leg, so that the bone may be easily severed and the animal can keeper is designed to beeng'aged by 'ger plate has that is fixed to the base 25.

.With my improvement the ceives therethrough the eye ends of a double spring 29 which, when expanded, swings the jaws 26 towardeach other in the usualmanner. The base 25 has approximately central- 1y "fixed thereonthe lower and shorter arm 30 of a two arm spring, the. outer armbeing indicated by the numeral '31. The spring is arranged transversely with respect 'to the base and the lower arm 30 (which may be in the nature of a rigid plate) has its free end reduced and formed with an upstanding ear 32 provided with openings in which are journaled the offset rounded and reduced ends or trunnions 4 1 formed on one of the ends of the arched 1nner aws 33. There 1S secured to the opposite end of the lower arm or plate 30 or there may be formed therewith an upstanding e'ar 35 having spaced openings through which are journaled the trunnions 36 on the'second ends of theinner jaws The ear 32 extends through anenlarged elliptical opening in the spring arm 31.

The pan is indicated by the numeral 37 and has fixed thereto in the ordinary man ner the bodyplate of the keeper 38; The a trigger usual construction. The trigan eye" end 10 that receives therethrough a transversely arranged lug or pin 41 formed centrally in an elongated round or elliptical opening 42 in a post 4:3 The mounting of the trigger is one of the important features of the present invention. Ordinarily the trigger is so mounted that the same can be swung between the outer jaw-s 26 which materially interferes with the setting of the trap. With my construction, and especially by reference to Figure 5 of the drawings it will be seen that the body of the trigger, when the same is swung upwardly, will contact with the inner face of the post 43 and cannot swing thereover.

The spring arm 31 has its outer and free end provided with the usual reduced extension 4: 1. Ordinarily there is pivotally mount- 7 ed on this extension a button which is swingable over one of they outer jaws 26. The button and the pivot therefor are easily rusted so that it is only with extreme diiiiculty that the button canbe brought to jaw-engaging position. The catch element, which I employ in lieu of the button, cannot become rustedto an extent that will prevent the'free opplate 39 of the do. I

, er edge of the finger,

. ing ends on which the ends of the eration thereof and also the catch member is automatically operated when one of the jaws 26 is swung to open position.

The end 44 of the spring arm 31 has an elongated opening 45 therethrough to freely receive therethrough the rounded body portion 46 of a catch 47. The body 46 is provided with around opening through which the outer end of the part 44 of the spring arm 31 is received. The catch has extending from its body an arm 48 and its body has its upper edge directly opposite the arm 48 formed with an outwardly extending lug 49 and also formed with a second lug 50 and an arched or rounded wall 51 between the lugs 49 and 50. When the jaw 26 is swung to open position the under face of the said jaw will contact with the outer face of the lug 49, thus swinging the catch to the dotted line position disclosed in Figure 6 of the drawings. The inner shoulder provided by the lug 50 will contact with the part 44 of the spring arm 31, thus holding the finger 48 in an upstanding position. It should be stated that the outbody and lug 49 are arched. The jaw, when swung below the lug 49 permits of the catch, incident to the weighted portion thereof provided by the finger 48, automatically swinging to initial position to bring the finger over the end 44 of the spring arm 31 to bring the under faceof the lug 49 to a position to be contacted by the outer and active edge of the jaw 26. The simplicity and advantages of this particular construction will be understood and appreciated by trappers and manufacturers of tra s.

lily improvement it will be readily attached to spring jaw traps of the ordinary construction. The improvements are of a simple nature, which may be cheaply manufactured and readily attached to ordinary types of traps and the advantages of my constructions will be fully understood by noted may be those skilled in the art to which said invention relates. I desire it understood, however, that I do not wish to be restricted to the precise details herein set forth and, therefore, hold myself entitled to make such changes therefrom as fairly fall within the scope of what I claim.

Having described the invention, I claim:
